Source Code
The code stays on GitHub. The author has not published this script under an open licence, so ForexR does not show its code. Copy script reads the file straight from GitHub into your clipboard, so you can still try it on your own chart. Ask the author before reusing the code anywhere else.
Overview
A standard buy triangle appears on a confirmed green bar that closes above the EMA and above the close two bars back, provided the previous bar was not red. An early buy circle appears when a green bar follows a green bar, touches the EMA but closes below it. A gate blocks signals when the bar touches both lines unless the prior bar was green and above the EMA. It has two alerts.
- EMA 9 line and Bollinger upper band
- Standard and early buy markers
- Band gate that blocks some signals
- Touch buffer in ticks for EMA and band
- Alert conditions for both buy types

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints. Check it in the Strategy Tester and on a demo account before you rely on it.
